Who NASA wants to fool???
First he said that can't take concrete/cement to the Moon. But for the 3D print using regolith (Lunar dust) he talks about polymers from plastic, took also from astronaut's trash (plastic used to put the food)
Ok, how much plastic they think astronaust's food carry on a ship??? Even if Homer Simpson was a astronaut they couldn't have enogh plastic to use the polymer for create enough for the mixing using lunar dust regolith.
